Not exactly sure if this is a super super super cheap deal, but it's still 48x 10G RJ45 ports with 4x QSFP ports. I know they are not super quiet, but turning down the fans to 40% keeps them cool and just slightly audible .... and it's ARISTA ;) All the other ARISTA switches I bought from them were all in super condition.

I was able to catch an offer for US$ 200.00. They, specially Tom, were very helpful with the process while eBay confused everyone again ;(

Really tempting considering the cost of SFP+ 10GBaseT transceivers...

Any idea how much power these draw at (or near) idle? And how loud are they?

110-130w estimate at idle
not loud at all, you can force the fans down

Ive also done business with them

what is the difference between tx and just t ?
T seems to have Broadcom Trident+, whereas TX has Broadcom Trident II.

Trident II has 33% bigger Buffer (9MB vs 12MB), Trident II supports VXLAN and NVGRE. Trident II has the smart table feature, which allows you to trade e.g. number of routes against MAC address table size etc..

7050T: EOS 4.18.x max
7050TX: EOS 4.28.x max

Seller accepted $175 for one

TBH, this seems like a great deal to me - I've been looking for one for a year, and they were selling for $450 not so long ago.

I can pull load numbers of similar model, marginally newer from a prod env, they are patching it up next week so I can pull numbers with all ports populated

with 6 ports I read 112w

2 to 5 watts for copper (distance) vs under 1w for SFP. There is a reason I use SFP everywhere except for OOB's.
How much did 2x Arista 10G SFP+ transceivers and fiber optic cable cost at the time and how much was electricity in 2014/15?
